overflow with ls

Description

With the 64-bit version of OSGeo4W, I'm seeing overflow with the ls utility while inspecting files larger than 4 GB. For instance, write three files that are near the 4 GB size where this is an issue, e.g. with Python

import os
os.chdir(r'C:\temp')
with open('f1.tmp', 'wb') as f:
    f.write(b'\x00' * (2 ** 32 - 1))
with open('f2.tmp', 'wb') as f:
    f.write(b'\x00' * (2 ** 32))
with open('f3.tmp', 'wb') as f:
    f.write(b'\x00' * (2 ** 32 + 1))

Now with either MSYS or the CMD.EXE-based OSGeo4W Shell (shown):

C:\Temp>dir *.tmp
 Volume in drive C is Windows
 Volume Serial Number is C0A8-5CF4

 Directory of C:\Temp

26/01/2015  02:14 p.m.     4,294,967,295 f1.tmp
26/01/2015  02:13 p.m.     4,294,967,296 f2.tmp
26/01/2015  02:27 p.m.     4,294,967,297 f3.tmp
               3 File(s) 12,884,901,888 bytes
               0 Dir(s)  13,467,774,976 bytes free

C:\Temp>ls -l *.tmp
-rw-r--r-- 1 mtoews Administrators 4294967295 Jan 26 14:14 f1.tmp
-rw-r--r-- 1 mtoews Administrators          0 Jan 26 14:13 f2.tmp
-rw-r--r-- 1 mtoews Administrators          1 Jan 26 14:27 f3.tmp

C:\Temp>where ls
C:\OSGeo4W\apps\msys\bin\ls.exe

Other tools like wc show the correct number of bytes, so I'm not sure where the issue is exactly or what other tools to check. I haven't checked with the 32-bit version of OSGeo4W either.
